Belle II has now accumulated the world's largest Υ(4S) dataset, surpassing Belle! Belle II's total integrated luminosity is 757 fb⁻¹ of Υ(4S) data and 864 fb⁻¹ of overall data. We hope to continue increasing the dataset for the rest of this data taking Run, which will continue until the summer.

As Belle II prepares for its future high-luminosity phases, experts from across the collaboration gathered at the Karlsruhe Institute of Technology, @kit.edu, for the 2025 Joint Computing, Data Production and Software Workshop for a week of in-depth discussions and collaborative planning.

Belle II has now published 45 physics papers, as of the end of last year. We look forward to publishing many more #belle2 papers in 2025! www.belle2.org/research/phy...

On our final day of data taking for 2024, the SuperKEKB accelerator broke the luminosity world record, and set a new record luminosity of 5.1 x 10³⁴ cm⁻²s⁻¹! Congratulations and Thank You #SuperKEKB! More information here: www2.kek.jp/ipns/en/news... (English) www2.kek.jp/ipns/ja/news... (Japanese)
